Calcium Alpha- Ketoglutaric Acid Powder
Description
Calcium Alpha- Ketoglutaric Acid Powder – Premium Grade Metabolic Support Ingredient
Shaanxi Nuoyuan Biotech Co., Ltd. proudly offers pharmaceutical-grade Calcium Alpha- Ketoglutaric Acid Powder with a guaranteed purity of 99% tested by HPLC. Our 30,000㎡ ISO 9001 certified plant with 20,000 tonnes yearly processing capacity ensures unrivalled stability and bioavailability.
The rapid degradation of pure alpha-ketoglutaric acid and the need for longevity compounds derived from non-animal sources are two major issues facing the industry that our approach tackles. We provide consistent quality for sports nutrition, anti-aging formulations, and therapeutic metabolic support applications worldwide thanks to our five state-of-the-art HPLC testing equipment and more than 15 years of OEM/ODM experience.
What is Calcium Alpha- Ketoglutaric Acid Powder?
Alpha-ketoglutaric acid (AKG), a critical step in the Krebs cycle for cellular energy production, is produced as a stabilised calcium salt. In an acidic environment, pure AKG rapidly deteriorates due to its extreme instability. This substance has improved gastrointestinal tolerance and shelf stability by binding AKG to calcium.
This white crystalline powder has two functions (CAS No. 71686-01-6, Molecular Formula: C5H4CaO5). It helps remove the ammonia that accumulates after intense exercise by acting as a nitrogen scavenger. Additionally, it is a precursor for the synthesis of glutamine and glutamate, both of which support metabolic health and muscle recovery.
This material is closely linked to cellular longevity processes and epigenetic regulation, in contrast to generic amino acid supplements. Because of this, it is the best component for both therapeutic sports nutrition supplements and biological age reversal formulae.

Manufacturing Process Excellence
Using modified strains of Yarrowia lipolytica yeast cultivated in a glycerol-based medium, our production method begins with biosynthesis. Without the use of nutrients originating from animals, this fermentation process ensures exceptional production and purity.
Following fermentation the alpha-ketoglutaric acid is precipitated as the calcium salt using pharmaceutical grade calcium carbonate (CaCO.sub.3). The process yields product with very high purity (above 99%).
Our 30,000㎡ facility contains modern extraction, concentration and drying equipment. 5 HPLC testing devices assist our quality control team in monitoring each manufacturing step. This means your formulations will be provided with a bioavailable ingredient that is consistently stable and works dependably in challenging production conditions and in premix applications.

Key Benefits and Professional Applications
B2C For Anti-Aging and Longevity Formulations:
The product addresses the ‘Hallmarks of Aging’ by regulation of the mTOR pathway and support of DNA methylation. They are also great for lowering chronic inflammation (inflammaging) and helping to regulate the epigenetic clock, which is great for your consumers looking to reverse biological age. High purity >99% provides safety for long term supplementation.
For Sports Nutrition and Recovery (B2B):
Elite athletes need quick ammonia detoxification following severe anaerobic activity. This chemical turns ammonia into glutamine, prolonging muscle exhaustion and facilitating protein synthesis. It remains active in the challenging pH environment of the stomach to intestinal transition making it a great choice for after exercise recovery matrices.
For Clinical Metabolic Support (B2B)
Because calcium and AKG are involved in both phosphate binding and bone mineralisation, they are beneficial in medical-grade formulations for kidney health and osteoporosis. In contrast to regular calcium salts, the material is immediately integrated into metabolic pathways and improves nitrogen balance in those with disorders that cause muscular atrophy.
